So, you have a sprite, you draw some graphics, you set cacheasbitmap=true... I can't seem to access the newly created bitmap data, to access the dispose() method.
[Code]...
I've started getting to grips with using the BitmapData class and a Transformation Matrix in the hope that I can start making some interesting image effects. However, at the moment Im having trouble figuring out how to shift the newly created bitmap so that any scale transformations are applied from the center rather than the top left corner. See here for example: [URL] The flower on the left is the original, the flower on the right is the new image created using "bitmapData.draw()". It has been scaled up to twice the size, but I want this to happen from the center of the image.
[Code]...
is it possible to get access to Flash's internal bitmap cache of an object when CacheAsBitmap is on ?
eg, something like:
var bmd:BitmapData = someDisplayObject.getCachedBitmapData();
if (bmd != null)
trace("stoked!");
else
trace("bummer. got to bmd.Draw(someDisplayObject) ourselves.");
I'm cutting my teeth in actionscript 3 on a game that has a character running through a world. So, I have set up my Hit Testing by using the bitmap data hit test method, since I figured my world is going to be destructible - it'd be nice to update the level and then redraw it and have the character interact with the new change. (That works beautifully) I am however; a bit confused as to how I have my hit Testing set up. I've been messing around with it, and it works for now - but I'm not sure why.. currently, I have a character set up by using a class I built and using a series of animations I created. So, this character has a walking and falling animation, etc. This is a movie clip.
Then there's a bitmap 'emptyBitmap' with bitmap data created - however; I never really added this as a child to the character. This is sized to the dimensions of my character. My level is created as a movielip, then it's drawn to a bitmap - when the level movieclip is changed, the bitmap redraws, and that's how this updates.

1: I upload an image
2: Without altering it,I make a copy of it and use it display to users in resized format
note: I won't display the original image.
3:Now when user deletes the resized image,i need to delete the image loaded as bitmap i.e. the original image which i won't be displaying
For that I used bitmap.bitmapData.dispose() method.But,it doesn't free up the memory taken by the bitmap.For instance at initial state the memory usage is 58 Mb and upon loading 3 images the size increases to 87 Mb.And when I delete all the images the size decreases to 81 MB only.
This is my scenario

So if i have a bitmap in a mc that doesnt animate (because i write directly into the bitmapdata) can i use CACHEASBITMAP?
View 3 RepliesI am trying to use the bitmapData.setPixels method to set certain pixels in the bitmap transparent.But no matter what I do, it always seems to set the pixel(s) black (non-transparent).Here is my code:
[AS]
bmpd = new ImageFromLibrary(0, 0);
bmpd.setPixel(0, 0, 0x00000000);
[/AS]
why its not setting the pixel(s) transparent?
I am using the floodfill method to colour-in sections of a bitmap image. That part is easy enough but the issue comes in with the way I am adding an effect to the colour fill routine.
To add the effect, first a copy of the bitmap data is created and floodfill is used on that instead of the original bitmap. Then the bitmapdata.compare method is used to set the alpha value of everything apart from the filled-in section to 0 and the result is saved in another bitmapdata. After that, a 1 px radius circle sprite is added to the stage and is being tweened to the image dimensions and its mask is set to the sprite which contains the result of the compare operation.
This works perfectly except for the fact that the fill sprite has to be tweened to the complete image dimensions irrespective of how small the area is being coloured-in since I am not able to find a way to get the dimensions of the fill area. I am doing an bitmap image update at the end of the tween and I have to disable user interaction till the tween is complete to avoid the errors which come in if another fill-in operation is started before the base image has been updated. If I could somehow get the dimensions of the fill area then the time during which I have to disable the user interaction will go down considerably.

I am using the draw() method of the BitmapData to encode a jpeg of part of the image. Now this should be easy enough given the object I want to draw to the bitmap is on the stage at design time so I know its location and dimetions exactly! Heres the code I have in place.
Code:
var myBitmapSource:BitmapData = new BitmapData ( street.width, street.height, false, 0x333333);
myBitmapSource.draw(street, null, null, null, new Rectangle( 96, 5, 571, 450 ), true );
I know for a FACT that no part of the street clip I am drawing out is in negative space, and it's registration is (0,0). However, it cuts off A lot of the top of my image. y=5 in the above rectangle is where I need the top to be, but it cuts the top off of the image... even if I change it to 0, it has no effect.
I have a script that randomly pops out circles all over the stage. However, I want them to disappear once I roll my mouse over them (and only the ones I roll over, not all the instances).So if I have code like this in a function:[code]And then I have a mouse_over function in the same class, how do I tell it to removeChild? Since the stars are instances of the object, they are giving instance names like instance67, which makes them hard to remove.
View 2 RepliesDo you need to have a destroy/dispose method on your Document Class? Say I have a Document Class that has the following
- mouse event listeners
- timers running and or enter_frame listeners
- class variables
Do I need to have a destroy or dispose method that:
- removes event listeners
- stops timers
- nulls class variables
Or is this only something I need in other objects (sprites, movieclips) that are added to the stage of the Document class?
I am completely new to actionscript although I do come from a OOP background. I have been asked to trial Flash and Actionscript 3 in particular - so I do come with a few preconceptions on how I expect actionscript to behave. I have a problem I donot understand. I have created a new class and to test it I use a simple test harness in the form of a .fla file.
The issue I have is when I create a new instance of the class and assign it to a variable, subsequent background changes to that instance of the class are not 'picked-up' when referenced through the variable. I would expect that given instance of class could be assigned to many different variables and any updates using one variable would accessible using any of the other variables.

I have a MXML button:
<mx:Button id="myButton1"/>
How do I create N number of Buttons with Actionscript: myButton2, myButton3, myButton4... myButtonN ?
And how to get the reference to the newly created buttons right after they are created? Like I should be able to do myButtonN.x = 100 right after it's created.
How flash setup a variable to handle the newly created movieclip?
Example:
this.createEmptyMovieClip("mymovie",2);
this.clientscroller.setScrollContent(mymovie);
Where did I set it up as a variable? I tried this and didn't work either:
this.createEmptyMovieClip("mymovie",0);
mymovie.createTextField("mytext",1,100,100,300,100 );
In the code I'm writing, I use a with block to reference a newly created object thus:

I am completely new to using Flash and AS, so I decided to start off with something that seemed simple enough, rotating an image. Turns out it's anything but simple. My initial idea was simply to have two layers, on one of which I had the image I wanted to rotate, and above that some other image that was transparent. I've had lots of problems with this but I have managed to hack my way through to some solutions. I would like for someone to confirm if I have understood these solutions correctly.
One problem was that I implement my images (which were BMP at first but now GIF) as Bitmap, and they sit in the library and on stage, so they're visible when I run my Flash movie. However I had problems figuring out how to access the rotation property of my Bitmap, and what I ended up figuring out is that apparently even if it's loaded on the stage and in the library, it can't be used by AS as such. So I ended up having to use Linkage and making a SkyClass, which I then use to make a Sprite, which I can then change the orientation of. But is that really how I have to access my Bitmap, even if I put it on the Stage designtime?

I have create a Flash EXE in AS3. At the time of launch the exe loads a XML from a web link to validate itself.
var urlRequest:URLRequest = new URLRequest("http://abc.com:8090/validate.xml");
var urlLoader:Loader = new Loader();
urlLoader.addEventListener(Event.COMPLETE, startLoad);
urlLoader.load(urlRequest);
I have also place a crossdomain.xml at the root. When I launch the EXE, the debugger shows "SecurityError: Error #2000: No active security context."I just found a strange thing that when I'm writing the code on the timeline, its working (no security errors). But when I'm writing this code in the document class its not working.

How to get access to the rest of images, which were added to the Display List with the same name "imageLoader".I tried to call it with the imageLoader.name property,but surely i do something wrong, as only errors appear in the output panel.

How do I access the methods of a dynamically created movieclip/object?
